For a few users who could become the target of particularly aggressive cyber attacks, Apple in iOS 16 as well as in iPadOS 16 and macOS Ventura implemented the so-called “lockdown mode”. Blocking mode - also called blocking mode or lockdown mode - offers extremely strong protection for devices of people who could be spied on and/or attacked because of their identity or their activities. The lock mode under iOS 16 on the iPhone restricts some functions and content of the Apple smartphone - including websites and apps. Some features cannot be used at all in lockdown mode on the iPhone.
When I read up on the subject, I naturally wanted to try it out myself. I noticed that Apple itself uses the term “locked mode” in its instructions, while in iOS 16 (at least on my iPhone 12 Pro) the settings say “blocked mode”. That's why I use the two terms side by side here, even if only one is mentioned in official instructions. Other than that, this is the step-by-step guide on how to enter lockdown mode / blocking mode on iOS 16 compatible iPhones:
When blocking mode is activated on the Apple iPhone, notifications may appear that indicate that certain functions of the system, an app or websites are restricted. In Safari, a banner also indicates that lockdown mode is active.
The security setting activated in this way on the Apple device, regardless of whether it is an iPhone, iPad or Mac, causes restrictions - especially with regard to data traffic on the Internet, in networks in general and with regard to external devices. Here is an up-to-date list of the main limitations that come with blocking mode on iOS, iPadOS and macOS:
What according to the official support document HT212650 but should continue to function without restrictions, i.e. telephone calls and text messages via iMessage or SMS. The emergency functions of the iPhone, such as the accident detection and Emergency SOS, active. You can also refer to Apple's support document for information on how to set specific apps or websites as exceptions to blocking mode / lockdown mode.
